• Variability of SSA grouped by both altitude and geographic region.

• Lo = PBL, Hi = FT. West = ~west of Mississippi, East = between Mississippi and East Coast, Atlantic = over the Atlantic

• Minimum 5-min duration legs in the PBL, 10-min duration legs in the FT. As much or more variability in the observations in one atmospheric location as between locations (exception Atlantic - FT has lower SSA’s)

• For the East and Atlantic data, the medians are statistically different (significant at the 1% level)
